Greenhouse gases such as CO2 and methane are believed to contribute to global warming. Dust is a common problem throughout all mining activities. Dust generated by vehicle traffic can be reduced through a variety of means. Where water resources are not limited, regular watering with mobile water trucks or fixed sprinkler systems is effec- tive. Otherwise the application of surface binding agents, the selection of suitable construction materials and the sealing of heavily used access ways may be more suitable. Dust emitted during beneficiation can be controlled by means such as water sprays, baghous- es and wet scrubbers. Captured dust can generally be returned to the beneficiation process
